IMPROVEMENT IN HOP-CRUSHERS.

Specification forming part of Letters Patent No. 182,054, datedSeptember 12, 1876; application filed January 25, 1876.

To all whom it may concern.-

Be it known that we, ADOLPH BAUMANN andFRmDR'IcH HoEPPNER, both of thecity, county, and State of New York, have invented a new and ImprovedMachine for Crushing Hops and other articles, which invention is fullyset forth in the following specification, reference being had to theaccompanying drawing, in which- Figure 1 represents a transversevertical section. Fig. 2 is a plan or top view.

Similar letters indicate corresponding parts.

This invention consists in the combination of two feed-rollers, bothbeing armed with teeth, with a toothed crushing-roller, and-with astationary and an adjustable crushing-surface, so that the lumps of hopsor other articles, on being thrown upon the feed-rollers, are firstbroken up and carried to the crushing-roller, and that, by the combinedaction of the crushing-roller and the crushing-stirfaces, the hops orother articles are finally reduced to the requiredfineness.

In the drawing, the letter A designates a frame, which is closed onall-sides, and which forms the bearings for the two feed-rollers B B andthe crushing-roller C. All these rollers are provided. on their surfaceswith sharppointed teeth, so that they take hold of the articles to becrushed, and one of the feedrollers is geared together with thecrushingroller, while the other feed-roller may be made to revolvesimply by friction, or it maybe geared together with the firstfeed-roller, so that both revolve in opposite directions.

The crushing-roller O revolves in .the direction of the arrow marked onit in Fig. 1, and it co-operates with a stationary crushing-sur face, D,formed on one of the sides of the frame A, and with an adjustablecrushing-surface, E, formed on an apron which is hinged to the frame A,and the-position of which in regard to the surface of thecrushing-roller can be regulated by set screws a and bindingscrews b.

Our machine is designed principally for grinding hops,'which, when takenfrom the bales or packages, form big lumps or cakes of more or lesscompactness. These cakes, on being thrown upon the feed-rollers B B, aregradually broken up, and the fragments pass down upon thecrushing-roller C. By the combined action of this roller and of thestationary crushing-surface D, said fragments are still further reducedin size, and the reduced fragments are finally crushed to the requiredfineness by the co-operation of the crushing-roller O with theadjustable crushingsurface E.

With the crushing-roller O is combined a clearing-plate, F, which fitsthe teeth of said crushing-roller, and serves to remove from these teethsuch particles as otherwise would be liable to clog the same. Thecrushingroller is composed of two disks, (1, which are firmly mounted onthe shaft 0, and which form the supports for a series of segmentalplates, from the outer surfaces of which project the teeth.

The feed-rollers are constructed in the same manner, so that all theserollers can be readily constructed of cast-iron.

What we claim as new," and desire to secure by LettersPatent, is

The combination of two feed-ro1lers,B B, having teeth on their surfaces,with a toothed crushing-roller, O, and with a closed frame, A, on oneside of which are formed a stationary crushing-surface, D, and anadjustable crushing-surface, E, all constructed and operatingsubstantially in the manner shown and described.

In testimony that we claim the foregoing we a have hereunto set ourhands and seals this 20th day of January, 1876.
